I own a penny auction website. I want to have an app created to connect to our website so that users can get instant push alerts on their phone when auctions they have bid on are ending or we have special promotions.

I want them to be able to do everything on the app that they could do on our website like bidding, browsing, buying, user profile, etc.

The app will need to connect to facebook as well so that users can share what they are bidding on and what items they win.
